Number of Infections and Incidence* per 100,000 Persons

*Annual incidence is reported as cases per 100,000 persons. Incidence is calculated by dividing the total number of infections with each pathogen by the population in the FoodNet surveillance system for that year.

*Data are preliminary†Listeria cases defined as isolation of L. monocytogenes from a normally sterile site or, in the setting of miscarriage or stillbirth, isolation of L. monocytogenes from placental or fetal tissue§Shiga toxin-producing Escherichia coli¶Surveillance not conducted for this pathogen in this year **Numbers of cases of postdiarrheal HUS in children aged <5 years††U.S. Census Bureau population estimates for the surveillance area for 2014. Final incidence rates will be reported when population estimates for 2015 are available.
